There are a couple of things you could try.

One would be to reinstall Kaspersky, then try uninstalling it again. The last time I installed Kaspersky it didn't mind Avast being installed alongside it so this may work without removing / readding Avast.

Another tool is the Installer CleanUp utility from MS that can help remove installer remnents when the bulk of the program has been removed but it still appears to be installed in the Windows interface.

If you're looking for a powerful and versitile start-up analysis and removal program my favorite in the past has been Autoruns by Sysinternals. That can help identify most startup routines and remove them.

** Usual disclaimer: always backup your data if you can't afford to lose it before doing things such as the above.
